Frequently Asked Questions

What is SUN1 gene deafness?
SUN1 gene deafness is a genetic disorder caused by mutations in the SUN1 gene, leading to autosomal recessive hearing loss due to inner ear development issues.
What symptoms are associated with SUN1 gene deafness?
Symptoms include hearing loss in one or both ears, sensitivity to loud noises, difficulty understanding speech, trouble hearing high-pitched sounds, and tinnitus.
How is SUN1 gene deafness diagnosed?
Diagnosis involves genetic testing, specifically NGS (Next Generation Sequencing), to analyze the SUN1 gene for mutations.
What is NGS genetic testing?
NGS is a advanced sequencing technology that can analyze multiple genes simultaneously, making it efficient for detecting genetic mutations.
How much does the NGS genetic test cost in India?
The cost for SUN1 gene deafness NGS genetic test at DNA Labs India is INR 20,000, inclusive of home sample collection.
Is the test covered by insurance?
Genetic testing is often not covered by insurance in India; it is advisable to check with your insurance provider beforehand.
How long does it take to get results?
Results are typically available within 3 to 4 weeks after sample collection.
What samples are required for the test?
The test requires blood, extracted DNA, or one drop of blood on an FTA card.
Is home sample collection available?
Yes, DNA Labs India offers free home sample collection for this test across various cities in India.
Can this test detect all causes of deafness?
No, this test specifically targets mutations in the SUN1 gene; other genetic tests may be needed for comprehensive analysis.
What should I do if the test shows a mutation?
Consult a geneticist or ENT specialist for management options, such as hearing aids, cochlear implants, or genetic counseling.
How accurate is the NGS genetic test?
NGS is highly accurate for detecting gene mutations, but results should be interpreted by a qualified genetic counselor for clinical relevance.
